MUST-SEE: "The Fugitive," 8 p.m., CBS. When the season started this seemed like a sure hit. Instead, it has wobbled and CBS has scrambled for an explanation. One goes like this: No new drama has done well in a timeslot where it faces an existing drama from one of the big-four networks. Uncontested dramas ("Boston Public," "Dark Angel") thrived; others didnt. So heres a solution: "CSI," which has gotten great ratings, is moving to Thursdays and is being replaced by "The Fugitive," which wont have to compete with NBCs "Providence." That may help this show, which has Tim Daly as a guy falsely convicted of murder. Tonight, hes one of a group of homeless people sent to a psychiatric ward. Sought by one set of authorities hes now controlled by another.

"Michael," 3:05 p.m., TBS. Nora Ephron skillfully directed this 1996 film about a seedy angel (John Travolta) sent to Earth for reasons that arent immediately clear. The result is a pleasant mix of comedy and drama.

"Diagnosis Murder," 7 p.m., CBS. This show moves to a tough time slot. Tonight it starts a two-parter in which a current murder might be linked to one Marks dad faced 50 years ago.

"Law and Order: Special Victims Unit," 9 p.m., NBC. A murder leads to a probe of sex addiction.
